[chromium] Increase JPEG decoding performance some more
​https://bugs.webkit.org/show_bug.cgi?id=78323

Reviewed by Adam Barth.

Source/WebCore:

Increase JPEG image decoding speed by another 9% (avg) according to libjpeg-turbo tjbench.

No new tests. Covered by many existing tests, all requiring subsequent rebaselines.

  • platform/image-decoders/jpeg/JPEGImageDecoder.cpp:

(dctMethod): Fast decode on the jpeg-turbo using ports (Chrome Android, Chrome, Chromium).
(WebCore::JPEGImageReader::decode): Select DCT method via a helper routine.

LayoutTests:

  • platform/chromium/test_expectations.txt: tests containing jpeg images that will require

rebaselines, mostly together in a group, but some other expectations unattended to at the
current time, spread changes throughout the file. The following lists changed tests for
chrome mac and win:

     3        [chromium] Increase JPEG decoding performance some more
     4        https://bugs.webkit.org/show_bug.cgi?id=78323
     5
     6        Reviewed by Adam Barth.
     7
     8        Increase JPEG image decoding speed by another 9% (avg) according to libjpeg-turbo tjbench.
     9
     10        No new tests. Covered by many existing tests, all requiring subsequent rebaselines.
     11
     12        * platform/image-decoders/jpeg/JPEGImageDecoder.cpp:
     13        (dctMethod): Fast decode on the jpeg-turbo using ports (Chrome Android, Chrome, Chromium).
     14        (WebCore::JPEGImageReader::decode): Select DCT method via a helper routine.
